So hi everyone, I'm a freshman in Physics and in a couple weeks I'm gonna start my second semester, with Chemistry and two exams of Classical Mechanics (Theoretical and Practical). In our first semester we had Calculus, Linear Algebra and C Programming. Since our Calculus program went as far as Multivariable Calculus I'd like to know how much I will use it, together with Linear Algebra. Will it be mostly multivariable or single variable calculus the one used? And then Linear Algebra, when will I get to really use Matrix Diagonalization and Vector Duality?
